Mass Effect 3: Leviathan DLC details Reaper origins

Second single-player ME3 DLC sends players on a race across the galaxy to discover a powerful weapon.

EA has announced second piece of single-player DLC for Mass Effect 3, due for release on Xbox 360, PlayStation 3 and PC later this summer.

Titled 'Mass Effect 3: Leviathan', the new content takes players on a race across the galaxy to find the Leviathan, a powerful weapon capable of destroying a Reaper.

The quest takes place during the events of Mass Effect 3, and will introduce new areas on the Citadel, new characters and two new weapons: the AT-12 Raider shotgun and M-55 Argus Assault Rifle.

"Something lurks in the dark corners of space, something powerful enough to kill a Reaper," read a post on BioWare's blog.

"Shepard must discover the most closely guarded secret in the galaxy before the Reapers silence it forever. Discover more about the origins of the Reapers as you race across the galaxy to find the Leviathan. Unravel the dark history of the Reaper Race before it is too late."

Mass Effect 3: Leviathan will cost $10 or 800 Microsoft Points when it launches later this summer.
